I have tried tonight on my personal computer with the latest revision of
Tianocore (rev1199).
Actually, there is two versions of the BeagleBoard UFEI upstream. There is the
original version.
And the version we are working on which reuses most of the framework we have
introduces for our development platform to avoid code duplication and
flexibilty.
This is the version I have tested, to build it you must use './build-next.sh'
instead of './build.sh'
Unfortunately, there are two patches you will need to apply. These patches are
pending and wait to be approved by the maintainers of their respective packages.
One of the patch in the source tree and the other one is attached to this email.

Subject: [PATCH] MdeModulePkg/DxeCore: Fix the loop to find the highest
memory region to fix the DXE allocations
There was a wrong assignment which could lead to an infinte loop in DXE core in some conditions..
